BACKGROUND: In 2004, a randomised phase III trial by the European Organisation for Research and Treatment of Cancer (EORTC) and National Cancer Institute of Canada Clinical Trials Group (NCIC) reported improved median and 2-year survival for patients with glioblastoma treated with concomitant and adjuvant temozolomide and radiotherapy. We report the final results with a median follow-up of more than 5 years. METHODS: Adult patients with newly diagnosed glioblastoma were randomly assigned to receive either standard radiotherapy or identical radiotherapy with concomitant temozolomide followed by up to six cycles of adjuvant temozolomide. The methylation status of the methyl-guanine methyl transferase gene, MGMT, was determined retrospectively from the tumour tissue of 206 patients. The primary endpoint was overall survival. Analyses were by intention to treat. This trial is registered with Clinicaltrials.gov, number NCT00006353. FINDINGS: Between Aug 17, 2000, and March 22, 2002, 573 patients were assigned to treatment. 278 (97%) of 286 patients in the radiotherapy alone group and 254 (89%) of 287 in the combined-treatment group died during 5 years of follow-up. Overall survival was 27.2% (95% CI 22.2-32.5) at 2 years, 16.0% (12.0-20.6) at 3 years, 12.1% (8.5-16.4) at 4 years, and 9.8% (6.4-14.0) at 5 years with temozolomide, versus 10.9% (7.6-14.8), 4.4% (2.4-7.2), 3.0% (1.4-5.7), and 1.9% (0.6-4.4) with radiotherapy alone (hazard ratio 0.6, 95% CI 0.5-0.7; p<0.0001). A benefit of combined therapy was recorded in all clinical prognostic subgroups, including patients aged 60-70 years. Methylation of the MGMT promoter was the strongest predictor for outcome and benefit from temozolomide chemotherapy. INTERPRETATION: Benefits of adjuvant temozolomide with radiotherapy lasted throughout 5 years of follow-up. A few patients in favourable prognostic categories survive longer than 5 years. MGMT methylation status identifies patients most likely to benefit from the addition of temozolomide. FUNDING: EORTC, NCIC, Nelia and Amadeo Barletta Foundation, Schering-Plough.

To provide an update to “Surviving Sepsis Campaign Guidelines for Management of Sepsis and Septic Shock: 2012”. A consensus committee of 55 international experts representing 25 international organizations was convened. Nominal groups were assembled at key international meetings (for those committee members attending the conference). A formal conflict-of-interest (COI) policy was developed at the onset of the process and enforced throughout. A stand-alone meeting was held for all panel members in December 2015. Teleconferences and electronic-based discussion among subgroups and among the entire committee served as an integral part of the development. The panel consisted of five sections: hemodynamics, infection, adjunctive therapies, metabolic, and ventilation. Population, intervention, comparison, and outcomes (PICO) questions were reviewed and updated as needed, and evidence profiles were generated. Each subgroup generated a list of questions, searched for best available evidence, and then followed the principles of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system to assess the quality of evidence from high to very low, and to formulate recommendations as strong or weak, or best practice statement when applicable. The Surviving Sepsis Guideline panel provided 93 statements on early management and resuscitation of patients with sepsis or septic shock. Overall, 32 were strong recommendations, 39 were weak recommendations, and 18 were best-practice statements. No recommendation was provided for four questions. Substantial agreement exists among a large cohort of international experts regarding many strong recommendations for the best care of patients with sepsis. Although a significant number of aspects of care have relatively weak support, evidence-based recommendations regarding the acute management of sepsis and septic shock are the foundation of improved outcomes for these critically ill patients with high mortality.

Purpose
The LUX-Lung 3 study investigated the efficacy of chemotherapy compared with afatinib, a selective, orally bioavailable ErbB family blocker that irreversibly blocks signaling from epidermal growth factor receptor (EGFR/ErbB1), human epidermal growth factor receptor 2 (HER2/ErbB2), and ErbB4 and has wide-spectrum preclinical activity against EGFR mutations. A phase II study of afatinib in EGFR mutation-positive lung adenocarcinoma demonstrated high response rates and progression-free survival (PFS).

Patients and Methods
In this phase III study, eligible patients with stage IIIB/IV lung adenocarcinoma were screened for EGFR mutations. Mutation-positive patients were stratified by mutation type (exon 19 deletion, L858R, or other) and race (Asian or non-Asian) before two-to-one random assignment to 40 mg afatinib per day or up to six cycles of cisplatin plus pemetrexed chemotherapy at standard doses every 21 days. The primary end point was PFS by independent review. Secondary end points included tumor response, overall survival, adverse events, and patient-reported outcomes (PROs).

Results
A total of 1,269 patients were screened, and 345 were randomly assigned to treatment. Median PFS was 11.1 months for afatinib and 6.9 months for chemotherapy (hazard ratio [HR], 0.58; 95% CI, 0.43 to 0.78; P = .001). Median PFS among those with exon 19 deletions and L858R EGFR mutations (n = 308) was 13.6 months for afatinib and 6.9 months for chemotherapy (HR, 0.47; 95% CI, 0.34 to 0.65; P = .001). The most common treatmentrelated adverse events were diarrhea, rash/acne, and stomatitis for afatinib and nausea, fatigue, and decreased appetite for chemotherapy. PROs favored afatinib, with better control of cough, dyspnea, and pain.

Conclusion
Afatinib is associated with prolongation of PFS when compared with standard doublet chemotherapy in patients with advanced lung adenocarcinoma and EGFR mutations.

Objective: The objective of this study was to determine utility scores for various chronic conditions. Design and setting: This study is a descriptive analysis. Health Utilities Index (HUI) scores for 20 chronic conditions were examined from the National Population Health Survey (NPHS) from 1994 to 1995. Patients and participants: 17 626 individuals were surveyed (54.3% women). Chronic conditions included: acne (requiring medication), Alzheimer’s disease, arthritis/rheumatism, asthma, back problems excluding arthritis, chronic bronchitis or emphysema, cancer, cataracts, diabetes, epilepsy, food allergies, glaucoma, heart disease, high blood pressure, migraine headaches, other allergies, sinusitis, stroke, stomach/intestinal ulcers and urinary incontinence. Interventions: Health Utilities Index-Mark III (HUI-Mark III) scores for patients with and without a NPHS-defined chronic condition were collected. Utility scores were examined according to age, gender and comorbidity. Main outcome measures and results: 42.6% of individuals reported having no NPHS-defined chronic condition. The most commonly reported health conditions were allergies other than food (17.6%) and rheumatism/arthritis (16.5%). The mean HUI-Mark III scores for patients without a health state was 0.933 ± 0.079. Individuals with Alzheimer’s disease (0.580 ± 0.263), stroke (0.676 ± 0.230) and urinary incontinence (0.698 ± 0.230) had the lowest overall HUI-Mark III scores. Utility scores decreased as age and as the number of comorbid conditions increased. Conclusions: This study provides health economists, researchers and policymakers with a reference for health utilities of various chronic conditions, different age groups, gender and comorbidities.

The validity of the Geriatric Depression Scale (GDS) short form was assessed in a geriatric affective disorders outpatient clinic (N = 116). The GDS was highly correlated with the Montgomery Asberg Depression Rating Scale (MADRS), and with optimal cutoff scores of 5/6, demonstrated a sensitivity of 85% and a specificity of 74.0%. The GDS appears to be a useful, valid screening instrument in this population.

Background Neuroleptics are commonly used to treat behavioral disorders associated with dementia. However, their safety and efficacy have not been well established in these patients. Method A meta-analysis of randomized, controlled (either placebo or active drug), double-blind trials published since 1966 (N = 16; 499 treated, 112 active controls, and 123 placebo) was conducted. Data were collected on proportion of patients with clinically significant improvement, significant side effects, and dropout rates. Results Pooled mean percentages of patients who improved (95% CI): all neuroleptics, 64% (54% to 74%); low potency, 63% (54% to 72%); moderate potency, 70% (56% to 85%); moderate-high potency, 62% (49% to 75%); and high potency, 69% (49% to 90%). Thus, no differences in efficacy existed between different potencies of neuroleptics. Therapeutic effect (neuroleptic minus placebo) was only 26% (14% to 38%). Treatment-emergent side effects were more common for neuroleptics vs. placebo (mean difference = 25%, 13% to 37%), but pooled mean dropout rates were not different (mean difference = 4%, -7% to 14%). Neither weighting by clinical trial quality (3 raters; weighted agreement, 83% to 92%) nor exclusion of poor quality trials changed the results. Conclusion Neuroleptics have small but significant efficacy over placebo in this population, and the efficacy rate is equivalent to the side effect rate. Comparing different neuroleptics shows they have similar efficacy, side effects, and dropout rates. Further study to determine more specific drug-responsive behaviors is needed to maximize benefits of these drugs.
